MIE ADR-1500 Instruction Manual
The following provides a brief overview of how to start a monitoring and
sampling run.
Before starting a run, a HEPA filter or optional 37-mm filter must be
inserted downstream of the optical assembly. The recommended 37-mm
filters are glass microfibre filters. If using the 5-micron PVC filters, use the
glass microfibre filters as a backing media when using battery power.
Equipment Damage At no time should the ADR-1500 be running without
a filter in place, otherwise serious damage to the internal components may
result.

Before initiating a measurement run it is advisable to perform the zeroing
and automatic internal check out sequences, to ensure optimal operation.
From the Operate menu, press the

for subsequent data calculations. The duration of a Zero Operation is
usually 2-3 minutes. After Zeroing is complete, the following screen should
be present:
